WINDOW-CONTROLLING DEVICE.

Application flied June 19, 1920. Serial No. 390,055.

Window-Controlling Devices, of which the following is a specification,reference being had'therein to the accompanying drawings.

The invention relates to a device for controlling the raising andlowering of windows and more particularly the WlIldOWS of automobilesand other vehicles.

The object of the invention is to provide a device of the characterreferred to, which will permit of a single support, having but one pointof attachment to the door of the vehicle, and carries both the arm,lifting the window, and also the counterbalancing spring for the window,together with the operating handle and locking mechanism. The device isparticularly adapted for use in connection with the type of windows usedin closed automobiles and other vehicles, which windows in opening havea lowering movement.

While the invention will be fully described in the followingspecification, and

while in its broader aspects it is capable of embodiment in numerousforms, I do not wish to be limited to the preferred embodiment thereof,as illustrated in the accompanying drawings, in which:

Figure 1 is an inside view of the door of a closed vehicle with myinvention applied thereto showing different positions taken by thewindow lifter arm;

. Figure 2 is a side elevation of the lifter device;

Figure 3 is a to view thereof;

Figure 4 is an inside view of the handle.

In the drawings: A represents a bracket member which is attached to thedoor of the vehicle. by any suitable means such as the screws B. In saidbracket member is journalecl a stub shaft 0, on which is mounted fastthe window lifting arm D, cut away at E to permit the installation ofsprings F. These springs are preferably formed by a continuous wirelooped around a fixed pin G on the bracket and extendingoutwardly to apredetermined point, the end portions of the wire forming said springs.

Said sprin are secured by any suitable means as the coped wire H, to apin I upon the free end of the lifter arm, which pin carries also thewindow liftin roller J.

Owing to the springs F being anchored that the latter may be shiftedeither up i.

wardly or downwardly through only a slig manual exertion.

To provide a means for positively holding the window in any positiondesired, an automatic locking means is provided as follows: Upon thebracket A is formed a circular row of gear teeth K. Upon the stub shaftC is mounted a handle or lever L, preferably extending parallel with thelifter arm and secured thereto in the following manner:

The .lever L is provided with a recess L for receiving a pin M on thestub shaft 0 and a spring N, which abuts against a head M on the pin andagainst the bottom of the recess L, thus tending to hold the leveragainst the bracket member. However, to operate and lock the windowlifter arm by means of the lever L, it is necessary to further providethe lever with corresponding circular gear teeth L for engagement withthe teeth K on the bracket member. As it is necessary to disengage theteeth in order to move the lifter arm, a pivotal connection isestablished between the lever L and an arm 0 on the stub shaft by meansof a pin O, the lever L being sufiiciently cut away at P to provide ahousing for the arm 0.

In the construction described, in order to raise or lower the window, itis necessary to first disengage the intermeshing teeth K and L thisbeing accomplished by pulling the handle or lever L outward, said handleswinging upon the pin 0 as a pivot. Then the lever L is rotated in thedesired direction which will likewise rotatethe window lifting arm, bothbeing non-rotatabl mounted upon the stub shaft as describe When thewindow is shifted to the desired position, the lever L is released, andthe tenthe entire operating mechanism, including the counterbalancingspring for the window. The advantages derived from this invention arebelieved self evident, such as, easy attachment, avoidance ofcomplication and the obvious result, a cheaper construction.

While I have described a preferable mechanism adapted to be used with avehicle door, I do not wish to be limited to any specific construction,arrangements or combination of parts as my construction is capable ofnumerous modifications and changes without departing from the scope ofthe invention. Although my invention has been illustrated in connectionwith a vehicle door it may of course be used in other connections.

What I claim as my invention is:

1. In a window operating device, a unit assembly comprising a lifterarm, a bracket forming a pivotal support for said arm, a counterbalancespring extending from said arm to said bracket and acting upon said armin the various positions thereof with approximate uniformity, andmeans-for. looking the arm to the bracket in various posi tions ofadjustment.

2. In a window operating device, the combination with a window liftingarm provided with an elongated opening, of a spring located in theopening of the arm and urging the arm upwardly, an operating means forrocking said window lifting arm and a bracket member-forming a slnglesupport for said device.

3. In a window operating device, the combination with a window liftingarm and an actuating handle therefor, of a journal member connectingsaid arm and handle and bracket wherein said journal member is mounted,latch elements respectively carried by said handle and bracket, and aspring urging said handle toward the bracket to normally establish latchengagement between said elements.

4. In a window operating device, the combination with a bracket and awindow lifting arm, of a journal member pivotally mounting said arm onsaid bracket, an actuating handle for said arm having pivotal connectionto said journal member,'the axis of said connection being transverse tothat of the journal member, latch members respectively carried inopposed relation by the bracket and handle member, and means urgingswinging of said handle member at its pivotal connection to said journalmember to normally engage said latch elements.

5. In a window operating device, the com bination with a pivotal windowlifting arm provided with an elongated opening extending longitudinallythereof and window counterbalancing means extending within the opening.

6. In a window operating device, the combination with a window liftingarm having an elongated opening and a bracket upon which said arm ispivotally mounted, of a window countcrbalancing spring extendingwithinthe opening.

7. In a window operating device, the combination with a window liftingarm, of a bracket, a shaft mounted in said bracket and carrying saidarm, a second arm rotatable with said shaft, a handle for rotating saidshaft, said handle being pivoted upon said second mentioned arm,cooperating latch elements carried by said bracket and handle, and meansfor establishing engagement be tween said latch elements.

In testimony whereof I aliix my signature.

STANLEY IV. NICHOLSON.
